What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Hamilton Jazzmaster Open Heart Auto

The Hamilton Jazzmaster Open Heart Auto is noted for its dressy yet versatile design, featuring striking gradient dials and intricately shaped cutouts that reveal the H-10 movement. It boasts an 80-hour power reserve and Nivachron hairspring. The watch is available in 36mm, 40mm, or 42mm stainless steel cases. On balance, the Hamilton Jazzmaster Open Heart Auto is appreciated for its visually engaging dial and movement display at its price point.

From video reviewers

The smoked dial's precision cutouts offer a captivating view of the automatic movement. Legibility is compromised by the open-heart design.

Phoibos Eagle Ray No Date

Owners widely praise the Phoibos Eagle Ray No Date for its value at the price point. One owner notes the watch is a great purchase with no regrets, and is unbothered by its lume. The Phoibos Eagle Ray No Date features a 41mm steel case and a Miyota 9015 automatic movement with a 42-hour power reserve. However, one owner received a non-working watch and reported difficulty obtaining a refund, citing horrible customer service. On balance, owners rate the Phoibos Eagle Ray No Date well for its value, though customer service experiences can vary.

From video reviewers

The Phoibos Eagle Ray No Date features a high-beat Miyota 9015 movement, which is a notable strength. A weakness of the watch is its relatively weak lume brightness. Reviewers disagree on whether the added features of the Ceramic model justify the extra cost, with one reviewer finding it worth the extra cost and another noting it's a trade-off for the No Date model.
